My invention relates to the type of desk pen stands having a holder adaptedto form a sealing cap for the forward end of a fountain pen, so as to receive and position the pen. 0

Generally speaking; my invention alms to provide a compact, inexpenslve and durable pen stand embodying these characteristics;

(1) Ready rotatability of the holder with I respect to the base of the stand.

(2) Ready tiltability of the holder to dispose that axis of the holder at any desired inclination, or horizontally.

(3) Effective frictional latching of the holder in any adjusted position. I

(4) Ready relaxing of this latching to facilitate rotational movement of the holder.

(5) Compensation for inaccuracies in the manufacture of various parts.

(6) Simple means for adjusting the tightness of the latching of theholder against both tiltable and rotatable movement.

(7) Single means for simultaneously making'both of these adjustments.

(8) A construction permitting almost all of the parts to be assembled as a unit and attached as such to the base.

Still further and also more detailed objects will appear from the following speci- 30 fication and from the accompanying drawin s, in which ig. 1 is a side elevation of a desk stand embodying my invention, showing this as supporting a capless fountain pen in a horizontal position.

Fig. 2 is an enlarged elevation of the assembly of parts before this is attached to the base by a clamping nut, and before the pen-receiving holder is attached to the 4 pivoted holder carrier.

Fig. 3 is a still more enlarged and fragmentary vertical sectiontaken along the line 3-3 of Fig.1, but with the pen-receiving holder in an upright position. 4

Fig. 4 and Fig. 5 are sections similar to a part of Fig. 3, showing two other embodiments of my invention.

In the embodiment of Figs. 1 to 3 inclusive, my pen stand includes a base 1 having has its lower ber in the form of a tubular fitting which has a flange 5 seating on the top of the base 1..

The shank 4 is threaded to receive. a nut 6 housed by the recess 3 and engaging the top of the recess to cooperate with the flange 5 for clamping the post rigidly to the base.

The bore of the tubular fitting comprises an upper and downwardly tapering portion 7 and a cylindrical bottom'portion 8, which bottom portion is larger in :diameter than the lower (smaller) end of the tapering bore portion, thereby'atfording. an inner annular and radial shoulder 9 at the top of the bottom portion 8.

Socketed in the tapering bore portion 7 is the correspondingly. tapered shank 10 of a post which has its upper end longitudinally slitted to'aflord spaced upper fork arms '11, and which has a longitudinal bore 12 extending downwardly from the space between the forkarms to the lower end of the post. Extending snugly between these fork arms and pivoted to the latteron a horizontal pin 13 is a lug 14 forming part of a carrier which also includes a threaded stem 15 and a relatively larger diametered stop flange 16 between this stem and the lug 14. A pen-receiving holder 17 of the usual caplike shape has its closed end threaded upon the stem and seated on the outer face of the stop flange 16.

The lug 14 preferably is of circular section transverse of the axis of the pivoting pin 13, and the periphery of this lug is engaged by a friction plug 18 which slidably fits the upper portion of the bore 12 of the post. This plug is continually pressed up- Wardly by a compression spring 19 interposed between the bottom of the plug and the tip of a screw 20, which screw is threaded into the lower end of the bore of the post, while another and desirably stronger compression spring 21 is interposed between the head 20 of the screw and the annular shoulder 9 of the tubular fitting. Thus arranged, the post and screw together constitute a post member'socketed on the supporting member.

With the parts thus assembled, the down-. ward pressure of the spring 21 on the head of the'screwacts through this screw to draw the tapering lower post portion tightly into the tapering bore portion of the tubular fitting, thereby creating a frictional resistance to a rotation of the post.

However, the post can be rotated by a suflicient effort, or with much less effort by first lifting the post slightly against the pressure of the spring 21 so that the tapering'post portion will clear the tapering bore portion of the said fitting.

Owing to the action of the upper spring'19 in pressing the plug 18 against the lug 14 of the carrier which supports the pen-receiving cap 17, this plug acts'after the manner of a brake to hold the carrier in any inclination to which it may have been moved, and by selecting a spring 19 of suitable strength I can secure this latching of the carrier While still permitting the inclination to be changed instantly and with but, slight effort on the part of the user. -However, by socketing a long tapering portion of the post in a correspondingly tapered portion of the supporting member and drawing.the post downward by a spring, I wedge the post in the supporting member so that the post will. not be accidentally rotated during the pivotal mov ment of the pen receptacle upon the post.

To enhance the appearance, I desirably machine the lug 11 of the carrier so that its periphery corresponds to the spherical contour of the fork arms 11; and with the peripheral lug portion thus convexed (as shown in Fig. 3) I desirably concave the upper end of the friction plug or brake 18, so as to have the plug engage a considerable portion of the said To avoid a sticking of this friction plug, I desirably make the same of a different material than the post and the carrieras for example by using brass for the post and carrier, while making the friction plug of hard fibre. The tubular fitting may be of the same material-desirably brass-as the post, since the post can readily be raised slightly away from its tapering seat, particularly when the fork arms are substantially knob-shaped (as in Figs. land 3) so that they can be digitally grasped for this purpose.

With the parts thus arranged, it will I be evident from Fig. 3 that all portions except the nut 6 and the base 1 can initially be assembled as a unit, and that the adjustment of the spring tensions can be made before this unitary assembly is attached to the base. Consequently, the manufacturer (and even the'deal- .er) can reduce his stock by carrying a supply of such assemblies and of the corresponding nuts, together with an assortment of bases of different styles, materials or colors, thus re- 'ducing both the required investment and the storage space. Furthermore, a mere rotational movement of'the screw 20 simultaneou sly adjusts the tensions of both springs, so that even the user can readily make this ad justment if he finds it desirable.

However, while I have heretofore described my invention in an embodiment in which both springs as well as the screw are housed bythe tubular fitting, in which the socketmg memthe spirit of my invention or from theappended claims.

' For example, Fig. 4 shows portions of another embodiment in which the tubular fitting 22 is relatively short and has no inner shoulder, and in which the head of the screw 23 is disposed below the said fitting. In this case, the spring 21 is interposed between the head of the screw and the lower end of the fitting Fig. 5 shows still another embodiment, namely one in which the upper bore portion 24 of the nipple or supporting member is cylindrical. In this case the post has a cylindrical shank 25 slidably fitting this cylindrical bore portion 24 and also has a flange 26 above its said shank, which shank seats on the upper end of the nipple.

With each of the illustrated embodiments, the upper spring 19 permits the plug 18 to move up or down to compensate for variations in the radius of the pivoting lug 14. Likewise, the spring 21 can be distorted to compensition and an adequate latching of the parts in adjusted position, without requiring a high degree of accuracy in the manufacture of the parts.
